EOR – Polymer Injection

The different mechanisms for the recovery of hydrocarbons from reservoirs has usually been divided into three types: primary, secondary and tertiary recovery mechanisms. Although this nomenclature suggests a chronological order among these stages, their application is subject to the specific characteristics of the reservoir and to the field production strategy. However, primary recovery is generally..

The application of sensitivity analysis to reservoir simulation

  Reservoir simulation involves the mathematical manipulation of a significant amount of information, most of which is subject to uncertainties due to factors such as insufficient measurements, lack of accuracy and spatial heterogeneities, as previously discussed. Consequently, it is imperative to quantify the impact of these parameters’ variations on the simulation workflows (modeling, analysis and..

Risk and uncertainty in petroleum exploration

It is well known and documented that exploration of hydrocarbons is inherently a high-risk activity given a large number of uncertainties that may be present at any particular stage. The most common uncertainties are related to geological features such as structures, seals, and faults. On the other hand, economic analyses present uncertainties related to costs,..

Upscaling: Building a reservoir simulation model

In recent years, continuous improvements in computing and software technologies have considerably enhanced several aspects of reservoir simulation techniques. Simulation runtimes have sharply decreased due to advancements in hardware and processing power. In spite of this, the level of detail built into a geological model continues to exceed the current computational capabilities. Typical reservoir simulators..
